CHAPTER REPORTS The Cornell Chapter During the academic year 191 5-16, ten meetings were held, at nine of which a scientific program was presented. Two meetings of especial interest were devoted to departmental demonstrations of research work under investigation by members in the depart- ment. The general policy of the chapter has been to invite the public to the lectures and demonstrations, and the large attendance in most cases has been good evidence of the interest shown in the work of the Society. The usual social hour for members and their wives was held immediately following many of the lectures. The list of meetings with speakers and dates is as follows : The Bearing of the Modern Study of Heredity on our Ideas of Evolution, by Dr. T. H. Morgan of Columbia University, October 18. Plant Life in the Cayuga Lake Basin, by Professor K. M. Wie- gand, November 23. The Habits of Spiders, by Professor J. H. Comstock, December 16. Some Present-day Ideas Regarding Soil Fertility, by Professor T. L. Lyon ; followed by an inspection of the new soil tech- nology laboratories, January 13. Industrial Electric Heating, by Professor C. F. Hirshfeld, Chief of the Research Department of the Detroit Edison Co., February 17. Experimental Demonstration of Research in Progress, by mem- bers of the Department of Psychology, and inspection of the psychological laboratories, March 23.

Dolley, Secretary. NOTES The Indiana Chapter has published a yearbook for 1916 which lists officers and members of the Chapter and the full program for the calendar year. One meeting is held in each month during the academic year and usually at each meeting two papers are read by resident members. The January meeting, however, is devoted to Convocation Week Reports by fifteen members and there are two meetings at which visiting scientists have delivered addresses. One unusual feature of the pamphlet is a full list of non-resident and former members of the Chapter. District of Columbia Chapter. — In the list of the Charter Mem- bers published in the Sigma Xi Quarterly, Volume 3, No. 2, June, 191 5, the name of Alden Archibald Potter, A.B.
